GL vs independent 11 Plus exams is the comparison that matters most for families applying across both the grammar and independent sectors. For 2026 entry, GL Assessment remains the dominant 11 Plus provider used by many English grammar schools, while independent senior schools often use the ISEB Common Pre-Test, their own bespoke entrance papers, or a combination of academic assessment, interview and written tasks.
CEM still appears in parent searches because of its historical role in grammar-school testing, but its paper-based 11 Plus route was discontinued in late 2022. For most families, the more useful modern comparison is no longer simply GL versus CEM, but GL versus ISEB, GL versus Consortium of Selective Schools in Essex, GL versus FSCE or GL versus bespoke independent-school assessment.
One of the most common mistakes parents make at the start of preparation is assuming that all 11 Plus exams broadly test the same thing in the same way. While many assessments overlap in English, maths, verbal reasoning and non-verbal reasoning, the structure of the papers, the way questions are presented, and the skills that carry the greatest weight can differ significantly.
A child prepared brilliantly for one format may still be underprepared for another if the preparation has not been carefully matched to the exam they will actually sit.
That is why identifying the live format used by each target school should always come before building a preparation plan.
The 11 Plus Provider Landscape for 2026
The 11 Plus landscape is more varied than many families first realise. Although people often speak about “the 11 Plus” as though it were a single exam, there are several distinct routes, each with its own structure, style and preparation priorities.
For grammar-school entry across much of England, GL Assessment remains the main provider and sets the benchmark format that many families encounter.
Within the independent sector, many leading schools use the ISEB Common Pre-Test as an initial screening assessment, often alongside later written papers and interviews.
In Essex, the Consortium of Selective Schools in Essex uses its own long-established examination model, which feels notably different from GL-style multiple-choice testing.
Alongside these sit a broad group of independent schools that write their own bespoke papers, often with substantial creative writing, extended English responses, mathematical working and interview stages.
The result is that 11 Plus preparation can mean very different things depending on where a child is applying.
GL Assessment: The Main Grammar-School Format
GL Assessment is, for many families, the main format to understand because it is widely used in grammar school admissions.
The structure is typically paper-based and multiple-choice, with separate answer sheets that require careful transfer of answers. English, maths, verbal reasoning and non-verbal reasoning often appear as separate papers or distinct sections within the wider assessment.
This format rewards familiarity with question types. Children who understand how verbal reasoning formats work, how non-verbal patterns are constructed and how to manage multiple-choice timing usually perform more confidently because fewer surprises arise on the day.
Speed matters, but speed built on method matters far more. A rushed child who guesses will often lose heavily to a calmer child who recognises patterns quickly and applies disciplined technique.
The widespread use of GL also means there is good availability of familiarisation materials, which gives families a clearer route into structured preparation.
ISEB Common Pre-Test: The Independent-School Screening Route
For many independent senior schools, particularly academically selective ones, the ISEB Common Pre-Test is a major first-stage assessment.
This feels very different from GL because it is adaptive and computer-based. Questions become easier or harder depending on how the child is performing, which means there is no simple sense during the test of whether things are going well.
That can be psychologically demanding for children who are used to fixed papers.
The assessment typically covers English, maths, verbal reasoning and non-verbal reasoning, and it places strong emphasis on sustained concentration, screen stamina and emotional composure. Children must keep applying sound methods even when question difficulty shifts unpredictably.
Preparation for ISEB, therefore, extends beyond content knowledge. Children need familiarity with adaptive testing, comfort working on screen, and the confidence to move forward steadily without overthinking previous answers.
Parents preparing for schools that use this route may also find How to prepare for the 11 Plus and independent school assessments useful.
Independent Bespoke Exams: A Broader Academic Challenge
Many independent schools go beyond the Common Pre-Test, either supplementing it or replacing it entirely with their own papers.
This is where preparation often becomes broader and more school-specific. English may include extended comprehension responses, grammar tasks, creative writing, analytical writing or summary work. Maths frequently requires a full working and a clear written method rather than simply choosing from multiple-choice options.
Interviews, group activities and wider discussion may also form part of the admissions process.
Because these assessments are school-specific, there is no universal template. One school may heavily reward polished writing and depth of thought, while another may focus more strongly on mathematical reasoning, academic curiosity or interview performance.
Families, therefore, need to verify each school’s live admissions route carefully rather than assuming that all independent-school entry follows the same pattern.
How to prepare for independent school interviews may be useful where interview performance forms part of the admissions process.
CSSE: The Essex Grammar-School Route
For families applying in Essex, the Consortium of Selective Schools presents a different challenge.
Unlike GL’s tightly structured multiple-choice format, CSSE papers place greater weight on written fluency, extended English answers and maths where method and presentation matter. There is less reliance on the answer-sheet transfer technique and more emphasis on how clearly a child can communicate understanding on the page.
This changes preparation priorities.
Precision of writing becomes more important, extended-answer stamina matters more, and pupils need confidence in explaining mathematical methods rather than simply landing on the correct answer.
Children who are articulate writers often find this format suits them naturally, while highly efficient multiple-choice performers sometimes need a deliberate adjustment in approach.
FSCE: A Newer Provider
FSCE recently took over as the entrance exam for the biggest grammar schools in Gloucestershire, having recently been used by Reading Boys and a few schools in Essex. This will be for the 2027 entrance. They do not provide past papers, but do offer some clues in their Familiarisation Papers offered at these schools. Their format cannot be pinned down at this stage, but as well as standard maths and English, their Reading papers included “critical thinking”, which relies not on recall or technique but the ability to apply common sense to certain scenarios.
What Happened to CEM?
CEM still appears frequently in parent searches because, for many years, it was discussed alongside GL as one of the two major grammar-school formats. That historical reputation lingers online, which is why many older guides are now outdated.
The important modern point is that CEM’s paper-based 11 Plus route was discontinued in late 2022, and many former CEM areas moved to GL-style testing. Limited online use remains in some contexts, but CEM no longer sits as an equal live national comparator in the way older advice suggests.
This matters because old GL versus CEM preparation advice often reflects a landscape that has already changed.
Families preparing for 2026 entry should focus on what their target schools are using now, not what they used several years ago.
GL vs Independent 11 Plus Exams: Format Comparison for 2026 Entry
| Format | Typically used by | Paper type | Main preparation priority |
|---|---|---|---|
| GL Assessment | Many grammar schools | Paper-based, multiple-choice | Question-type mastery, timing and answer transfer |
| ISEB Common Pre-Test | Many independent senior schools | Online, adaptive | Adaptive strategy, screen stamina and composure |
| CSSE | Essex grammar schools | Paper-based, extended answer | Written fluency, method clarity and stamina |
| Independent bespoke | Many independent schools | Varies by school | Writing quality, maths working and interview readiness |
| FSCE | Gloucestershire from 2027, Reading Boys | Mixture | Maths, English, critical thinking |
| CEM | Limited modern relevance | Mainly online contexts | Verify the current live school format |
The key practical takeaway is simple: preparation must match the format.
A child sitting GL and ISEB simultaneously needs broader preparation than a child focused purely on one route. A child sitting CSSE needs different habits from a child sitting a purely multiple-choice grammar-school test.
This is why generic 11 Plus preparation can be inefficient. The closer the preparation matches the real assessment, the more useful it becomes.
Which 11 Plus Format Is Hardest?
Parents often ask which exam is hardest, but there is no single answer because difficulty depends heavily on the child’s strengths.
A child who thrives on fast recognition and crisp multiple-choice technique may find GL suits them well. A thoughtful child with strong concentration and a calm temperament may adapt effectively to ISEB’s adaptive structure. A strong writer may flourish in CSSE or bespoke independent-school papers where extended answers matter more.
The harder exam is usually the one least aligned with a child’s natural strengths and least well prepared for.
That is why the better question is not “Which exam is hardest?” but “Which format does my child actually need to be prepared for?”
How Lionheart Education Matches Preparation to Format
Lionheart Education begins by confirming the live admissions route used by each target school, because good preparation starts with clarity.
Once the format is established, preparation can be shaped precisely around what the child will actually face. That may mean GL-style question-type mastery, ISEB adaptive confidence, CSSE written fluency or broader independent-school preparation involving papers, writing and interviews.
That format-first approach prevents wasted effort.
Rather than preparing vaguely for the 11 Plus, children prepare specifically for the assessments that matter to them. The result is sharper focus, stronger confidence and preparation that reflects the real exam landscape rather than outdated assumptions.
